Sciacca (o1. V:issoi i The present invention relates broadly toimprovementsin cutting tables generally, and more particularly to such atable adapted primarily for use in the cutting of sheets or platesofglass and the like.

An important object of this invention resides in the provision of acutting table of `simple practical design by the use of which itispossible to effect a rapid and accurate cutting of the glass sheets orplates toa predetermined shape and size. i i' Another important objectof this invention resides in the provision of such a cutting table ofthe character above described which is adaptable for the cutting of theglass sheets or plates into various shapes and sizes. l

Other objects and advantages of the' invention will become more apparentduring the course of the following description whentaken in connectionwith the accompanying drawings. Y In the drawings forming a partV ofthis application and wherein like numerals 'are employed to designatelike parts throughout the same,`

Fig;v 1 is a plan view ofacutting table conl structed inaccordance withthe present invention; Fig. 2 is a section taken substantially 'on line2 2 of Fig. 1, j;

Fig. 3 is a plan view of a slightly modified type of cutting table, y i

Fig. 4 is a section taken substantially on line 4-4 of Fig.. 3, and Fig.5 is a section taken substantially on line 5-5of Fig. 3. C Referring nowto the drawings, `and particularly with reference `first to Figs. 1 and2, the top ofthe cuttingrtable herein providedv is designated in itsentirety by thefnumeral II) and is adapted to constitutea horizontallsupport or bedV upon which the glass sheet or plate II vto be cutislad.The table topi I ispreferably of4 allaminated or compound construction,being l composed of a plurality, and as hereshown three, superimposedlayers ofwood I2, ,t3` and I4 respectively, with the grain vof they woodin one layer running at an angle'to the grain Vof the wood'in theadjacent layer so as tostrengthen the compound topas well as to prevent.warping of the wood in the respective layers. Each layer may be formedof a single board or,` if desired, each layer may be formedof aplurality of strips or pieces shaped so as to'lie` snugly and closelytogether. The wooden layers I2, I3 and I4 may be surroundedfby arectangular wooden frame I5,

Secured upon `the vupper'surface of theV top I0 is a preferably metallicplateIE formed with a plurality of spaced parallel longitudinallyextending slots I'I anda plurality of spaced parallel transverse slotsI8 which intersect and cross the said` longitudinally extending slots.The slots I'l preferably extend substantially the entire length of thetable while the transverse slots I8 extend substantially the entirewidth thereof.

Supported upon and secured to the metal plate I6 is a pad I9 preferablyof cork or the like, and this pad is likewise provided with a pluralityof longitudinally extending and transverse slots similar to and invertical alignment with the slots I'I and i8 in the metal plate I6.However, the longitudinally extending and transverse slots in the pad IBare preferably, though not necessarily, slightly wider than the slots l1and I8 in the metal plate l as indicated at 2u in Fig. 2. rIhe glasssheet or plate II to be cut is adapted to be Supported directly upon theupper surface of the pad I9. The wooden frame I5 preferably projectsupwardly beyond the wooden layer I4 of the table top and terminatesflush with the upper surface of pad I9. Mounted upon the top of thetable and extending longitudinally thereof is a strip ZI made of anysuitable material, while also mounted upon the table isa similarbuttransversely arranged strip`22. `These strips 2l and 22 are adaptedto be moved to any desired position upon the table dependent upon theshape and size of sheet to be cut, and are adapted to be engaged by theadjacent edges of the glass sheet or plate to eiect proper positioningthereof'during cutting. For instance, as here shown, the rearlongitudinal edge 23 of the glass sheet II abuts the strip 2|, while theleft hand end edge 2 of the sheet abuts stripV 22. v

In order to provide for the movement of the 'strip 2l `to the desiredposition upon the table, the said strip is carried by one or aplurality` of vertical bolts 25, each of which passes downward- `lythrough the said strip and also through certain of the transverse slotsI8 in the pad I9 and plate IG, the lower end of the bolt being receivedwithin a recess 26 in the`top of the table and having threaded thereupona nut 21. Uponloosening of the nutsl 21 by'rotation of bolts 25, thewooden strip 2`I" can be moved either transversely of the table orlongitudinally thereof` due to the fact that the longitudinal andtransverse slots `IIwand Iii` intersect and cross oneanother. It will,of` course, be understood that the recesses 2B in the top of the tableextend both longitudinally and transversely thereof beneath and invertical alignment with the slots I'I and I8 inmetal plate I6.

The strip 22 may likewise be secured in xed position by a bolt 23similar to bolts 25 so that this strip can also be moved bothlongitudinally and transversely of the table, during which time the bolty28 slides along within the slots I1 or I8.

Carried by the table top Ill is a rectangular frame 29 comprising thefront and rear longitudinally extending members 3U and 3l and theconnecting transverse end members 32 and 33. This frame may be hinged tothe tcp of the table at the rear thereof by a plurality of hinges 34 andmay also be provided With a handle 35 to facilitate raising and loweringthereof. The frame 29 is preferably of such a size that, when in loweredposition, it will be disposed `directly above the wooden frame I 5.

In the cutting of a glass sheet or plate II on the cutting table abovedescribed, thestrips 2| and 22 are first secured upon the table in theproper positions to give the desired size of cut and, by reason of thebolts 25 and 28 operating within slots Il and I3, the said strips may bemoved either longitudinally or transversely of said table. The strips2I'and 22 are so arranged that the distance between the inner edge ofthe strip 2| and the outer edge of the front member 30 of frame 29 issubstantiallyequal to the width of sheet desired, while the distancebetween the inner edge of strip 22 and the outer edge of the end member33 of frame 29 is substantially equal to the length' of sheet to be out.The frame 29 is then raised and the glass sheet I I laid upon the top ofthe table, with the rear edge 23 thereof in engagement with strip 2l andthe end edge 24 thereof in engagement with strip 22. The frame 29 isthen lowered to rest upon the sheet. When the sheet is so positioned, itwill be seen that the same projects outwardly beyond the frame members3i! and 33, and it is these projecting portions of the sheet which areto be removed. The cutting of the glass sheet may then be effected withthe aid of an ordinary hand cutter 36 including the usual steel cuttingwheel or diamond 3'I,`said sheet being scored by drawing the cutteralong and in engagement with the outer edges of the frame members 38 and33 which serve as the straight edge. vAfter the sheet has been scored,vit is 'adapted to be broken along the score lines in the usual fashionand, to facilitatev this breaking of the sheet, upper corner of theframe I may be bevelled as indicated at 38. Of course, the cutting wheelor diamond which is used to score the sheet will be spaced slightlyoutwardly of the frame as shown in Fig. 2, and this distance, which isusually approximately one-sixteenth of an inch, must be taken intoconsideration when initially positioning the strips 2l and 22 upon thetable.

FromA the above, it Will be apparent that there has been provided acutting table of simple, practical design by the use of which glasssheets or plates may be rapidly and accurately cutto a predeterminedshape and size. The cutting table herein provided is particularlydesirable for use in the cutting of a large number of sheets or platesof the same size. In other words, after the strips 2I1 and 22 have beenproperly adjusted upon the table, any desired number of sheets can becut without further adjustment, with the result that the necessity ofmeasuring each individual sheet andthen scoring the same with the aid ofal conventional straight edge is eliminated. This cutting table is alsoparticularly advantageous for us in the cuttting of relatively smallsheets or pieces of glass, and especially those that must be cut towithin fractions of an inch.

The present invention also contemplates the provision of a cutting tablewhich is adaptable for the cutting of glass sheets or plates of varyingshapes and sizes. Thus, this may be accomplished by substituting for therigid rectangular frame of Fig. l an adjustable frame such as shown inFigs. 3, 4 and 5. The cutting table disclosed in Fig. 3 is of the sameconstruction and arrangement as described hereinabove, with theexception of the adjustable frame which is designated in its entirety bythe numeral 39. This frame comprises the front and rear longitudinallyextending members IIE and 4I and the end members 42 and 43. The rearlongitudinally extending member 4I is hinged to the top of the table bymeans of hinges 44, and the end member i2 is rigidly connected withmember 4I. However, the adjacent ends of the end member il and frontmember 4D overlap one another and are pivotally connected together by ascrew 135. The front member MI is further provided at its opposite endwith a longitudinally extending slot t5 through which projects a screw47 secured to the end member i12. The opposite end of the end member 133is likewise provided with a longitudinally extending slot 48 throughWhich is received a screw i9 secured to the adjacent end of member il I.With such a construction, and due to the endwise sliding movement of theframe members ft2 and 43, coupled with the fact that they are pivotedt0- gcther as at 45, will permit of them being adjusted to assumevarious positions asshown by the broken lines in Fig. 3, with the resultthat it is possible to vary the contour of the frame 39 and therebyeifect the cutting of the glass sheets into different shapes and sizes.The frame 39 may also be provided with a handle 50 to facilitate raisingand lowering thereof.

It is to be understood that the form of the invention herewith shown anddescribed is to be taken as the preferred embodiment of the same, andthat various changes in the shape, size and arrangement of parts may beresorted to without departing from the spirit ofthe invention or thescope of the subjoined claims.
